Konstantinos Logothetopoulos (Κωνσταντίνος Λογοθετόπουλος) was a distinguished Greek medical doctor who became Prime Minister of a quisling government during the Axis occupation of Greece.

Logothetopoulos was born in Nafplion in 1878. He studied medicine in Munich and remained in Germany, practicing and teaching medicine until 1910, at which time he moved to Athens. In Greece, he founded a private clinic and served in the First and Second Balkan Wars as a doctor. He was discharged in 1916 resuming private medical practice until 1922 when he was again conscripted during the Greco-Turkish War to serve in the Army Hospital of Athens.

After the end of the war in 1922, Logothetopoulos became professor of gynaecology at the University of Athens. Eventually he became Dean of the University. During his tenure at the university, he taught and supported many young doctors in their studies including future politician Grigoris Lambrakis.

When Greece capitulated to the Germans in World War II, Logothetopoulos, who spoke fluent German and was married to a German woman, was appointed Vice President and Minister of Education in the first quisling government of Gen. Georgios Tsolakoglou. He served as Prime Minister between December 2, 1942 and April 7, 1943 when he was replaced by Ioannis Rallis.

When the German army left Greece in 1944, Logothetopoulos followed them to Germany. Eventually he was captured by the American army who surrendered him to Greek authorities in 1946. He was tried and convicted of collaborating with the enemy and sentenced to life imprisonment but was released in 1951.

Logothetopoulos died on July 8, 1961 shunned by his fellow Greeks.
